A velocity-time graph from t = 0 to t = 5 s shows velocity increasing linearly from 0 to 20 m/s. What is the constant acceleration?

Explanation:
Constant acceleration means the velocity changes by the same amount each second. On a velocity-time graph, acceleration is the slope of the line. Here velocity increases from 0 to 20 m/s in 5 seconds, so the slope is (20 − 0) / (5 − 0) = 4 m/s^2. Therefore, the constant acceleration is 4 m/s^2.
